Forty-seven specimens of Neotropical cormorants, Phalacrocorax brasilianus, from Lago Guaíba, Guaíba, State of Rio Grande do Sul, Brazil (30° 00' S, 51°15' W), were examined for helminth parasites between 1999 and 2003. Twenty species of helminth parasites were found: ten digeneans: Austrodiplostomum mordax, Austrodiplostomum compactum, Clinostomum sp.,

Journal of Ornithology, 2005
We investigated chick development and feeding rate in the neotropic cormorant, Phalacrocorax brasilianus, in a colony in Central Chile. The year of our study was characterized by relatively good foraging conditions. Brood sizes varied from two to five chicks, and hatching was asynchronous, with gaps of 0 to 6 days between the youngest and the oldest ...

Cardiovascular physiology of embryonic neotropic cormorants (Phalacrocorax brasilianus)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative PhysiologyCardiovascular maturation in avian species has primarily been studied in precocial species of birds, with few studies conducted on altricial species, which make up the majority of avian species. In the precocial species of birds studied to date, cardiovascular regulation is derived primarily from an adrenergic receptor stimulation that is present from ...

Flutuações sazonais na abundância de Phalacrocorax brasilianus (Gmelin) no estuário do Saco da Fazenda, Itajaí, Santa Catarina, Brasil [PDF]
Revista Brasileira De Zoologia, 2002 The Neotropic cormorant is one of the most comm on estuarine birds along SantaCatarina's shore, especially in artisanal fishery areas, where it obtains food easily. During the period from January, 1996 to December, 1999, and of January to December, 2001, the cormorants were monitored monthly in the estuary. The population P.

The advances of molecular techniques have increased the development of cost and time-effective libraries of molecular markers, such as microsatellites, which allow us to estimate genetic parameters in order to characterise species' population structures.

The parasite community structure of the neotropical cormorant, Phalacrocorax brasilianus, from two lagoons (Coyuca and Tres Palos) from Guerrero state, México, was examined. Fourteen species of adult helminths (6,391 individuals) from 48 cormorants were identified: 9 digeneans, 1 acanthocephalan, 1 cestode, and 3 nematodes.

ABSTRACTWe present the ecological functions of cormorants and estimate the economic value of these functions to artisanal fishermen, as a valuation exercise for Neotropic Cormorants at Los Olivitos Estuary, Lake Maracaibo, Venezuela. Ecological functions were based on estimating the abundance, distribution and diet of cormorants; economic values were ...

The Trinity River (Texas, USA) has been historically known as a polluted river because of its proximity to the Dallas-Fort Worth area and because of known discharges of sewage and agricultural irrigation waters to the river. Surprisingly, there are no studies regarding the presence of legacy contaminants in the river and their impacts to wildlife.
